"Within every living being, there exists an invisible chain of lifespan. There may be vast differences among beings before they break the boundary between mortal and god, but after breaking that divine boundary, they are all the same."
"This chain is also called the Longevity Lock."
"Below the True God Realm, even the most powerful beings are constrained by the Longevity Lock. The greatest among them reach the Ten Thousand Years Realm. Even with Longevity Divine Medicine, they can at most live for one 'hui'—that is, ten thousand eight hundred years."
"At least, that's what my inherited memories say."
The Black Dragon continued, sharing all the information he knew.
"Has no being ever opened the Longevity Lock without first breaking through to the True God Realm?"
Yang Chan asked curiously.
'If it's a lock, there must be a way to open it.'
"I've never heard of such a thing!"
The Black Dragon shook his head upon hearing this.
